Chitosan—the miracle biomaterial as detection and diminishing mediating agent for heavy metal ions: A mini review

The Application of Chitosan-Based Adsorbents for the Removal of Hazardous Pollutants from Aqueous Solutions—A Review

“…As the authors noted, this solution may have great potential for the construction of portable sensors for on-site and real-time Hg(II) detection in the future. As chitosan, due to its properties and availability, is currently one of the most frequently applied functionalizing agents used in various materials, both for the removal of metal and metalloid ions (which constitute a major part of aquatic pollution) and for sensing them, it has been recently called "the miracle biomaterial" [83].…”

Current trends in the detection and removal of heavy metal ions using functional materials

“…When the adsorbent contains a probe, it can enhance the mechanical properties of the adsorbent and stabilize the probe, thereby improving water treatment efficiency. So far, significant research has been devoted to establishing various functional materials, including nanomaterials, 22,23 polymer materials, 24,25 porous materials, [26][27][28] and biomaterials, 29,30 for the treatment of heavy metal ions with low detection limits, high sensitivity, high selectivity, and large adsorption capacity. Each functional material possesses unique advantages and holds great potential in addressing the issue of heavy metal ion pollution in practical applications.…”

Quantifying arsenic and mercury in aqueous media via bio-inspired gold nanoparticles modified by mango leaf extract

“…[6][7][8] Mercury and arsenic concentrations in water are permitted to be no more than 6 ppb and 10 ppb, respectively as per the World Health Organization's guidelines. [8][9][10] Monitoring metal ions in water has become a difficult task for the scientic community because of the increased application of heavy metal ions in industrial domains. [11][12][13] There are numerous methods, including atomic absorption spectrometry, atomic uorescence spectrometry, and inductively coupled plasma mass spectrometry, to nd metal ions in water.…”

“…Chitosan, a biodegradable biopolymer, is used as a reducing agent in the manufacture of gold nanoparticles. [5][6][7][8][9][10][11] These environmentally benign, biochemically mediated gold nanoparticles can be utilized to nd heavy metals in aqueous medium.…”

“…The most dangerous and harmful ions are mercury(II) and arsenic(III), whose consumption can lead to a variety of health issues, including brain damage, kidney failure, skin cancer, nervous system issues, etc. [6][7][8] Mercury and arsenic concentrations in water are permitted to be no more than 6 ppb and 10 ppb, respectively as per the World Health Organization's guidelines.
